what effect does acid rain have on limestone building and statues . write down a balanced symbol equation

acid rain wares down limestone

CaCO3+2HCl ===> CaCl2+ H2O + CO2

How is acid rain formed

There are three main causes of acid rain, but both are due to the same gases being released into the atmosphere. Acid rain is caused by the two main air pollutants, sulfur dioxide and nitrogen oxide. When these gases come into contact with the hydrogen and oxygen molecules in water they combine to form a weak acid. The major cause of acid rain is air pollution by burning fossil fuels, smelting metals and motor vehicles. Acid rain can also be caused naturally by the eruption of a volcano. When a volcano erupts it produces a large amount of sulfur dioxide and it is not uncommon to have acid rain. Acid rain can also be caused by lightning strikes as these naturally produce nitrogen oxide.

when the metal carbonates reacted with hydrochloric acid they formed :

a metal chloride , water and carbon dioxide
